XXVII.—An Examination of the Halticide of South America. 
By the Rev. Hamier Crark, M.A., F.L.S. 
I wave spent part of my short autumn holiday in the revision of my 
notes on the Dejean genera and other new forms of Halticide found 
in South America. As a rule, the groups formed by Dejean and 
Chevrolat in the 3rd edition of the Catalogue are natural, and for 
the most part good. It has appeared to me that the confirmation 
of old recognized names is so preferable to the creation of new ones, 
that it may be worth while to send the results of my investigations 
to the Editor of the ‘Journal of Entomology.’ In the following 
pages I have sought to establish the Dejean nomenclature, and have 
ventured in addition to introduce new genera, based on forms in my 
collection which have more recently been sent over by collectors. 
In my examination of the collections which I received from the 
Marquis La Ferté, M. Chevrolat, and M. Thomson I have been 
specially struck by one result of my inquiry; that is, the remarkable 
concurrence of testimony which these collections offer, not only as 
to the fixity of the Dejean genera, but even with regard to the 
identity of the several species. It is the fashion to some degree 
now a days to decry manuscript names, as being an unmitigated evil ; 
I have no special love for them; I cannot appreciate the usage 
which obtains among our continental friends of affixing to every 
species some name before it is admitted into the cabinet; but, on 
the other hand, there are instances, and the case before us is one,
